Research

My research is focused on the bioactive properties of two specific lipids: Dihydrosterculic acid (DHSA) and linoleic acid. DHSA is a cyclopropene fatty acid that is found naturally in cottonseed oil and it blocks endogenous lipid synthesis and cholesterol biogenesis. I am actively pursuing methods to assess its ability to treat hyperlipidemia and hypercholesterolemia in animal and human models. My work in the bioactive properties of linoleic acid has centered on its role in modulating skeletal muscle myogenesis and mitochondrial biogenesis. As a long-chain omega-6 polyunsaturated fatty acid, it promotes transcriptional activity via nuclear receptor-DNA interactions and more recently I have found that its ability to induce angiopoietin-like protein 4 production in muscle significantly impairs the capacity for muscle differentiation and metabolic function. The purpose of my research is to help restore normal metabolic function in disease states using molecular biology and biochemistry to understand how macronutrient metabolism is regulated in cell and animal models.
